Faced with constantly rising energy costs, renovation professionals are seeking effective solutions to reduce homeowners' consumption. Insulating unused attic space appears to be a relevant response to this issue. Among the materials available on the market, cellulose insulation for its performance and excellent value for money.
Current context
A high energy bill
The building sector is one of the largest consumers of energy. According to the French Environment and Energy Management Agency (ADEME), it accounts for nearly 45% of national consumption. Reducing the energy bill for a home or building is one of the main challenges facing property owners.
The impact of insulation on energy costs
Before undertaking any other work, it is important to check the condition of your thermal insulation. High-quality insulation is essential for reducing a building's energy consumption. Poor insulation can lead to heat loss of up to 30%, thereby increasing your energy bill. Furthermore, it is not recommended to change your energy source before checking the condition of your thermal insulation; rather, you should do the opposite. This is because if your home has heat loss, this will still be an issue after you have installed a heat pump, for example.
Insulating unused attic space is therefore often the first step recommended during energy renovation work in order to start saving energy.

The advantages of cellulose insulation
cellulose insulation an environmentally friendly and high-performance insulation material. Produced from selected fibers sourced from the paper industry, it offers excellent thermal and acoustic insulation. What's more, it is quick to install and now costs about the same as blown mineral wool.
cellulose insulation must be blown cellulose insulation attic spaces by a professional, in accordance with DTU 45.11, which governs this application. Compliance with regulations is crucial to ensuring the longevity of this material.
cellulose insulation also a bio-based material with a very good carbon footprint: its raw material comes from recycling and is collected locally. Its manufacture requires neither water nor heat: "simple mechanical grinding" is all that is needed to obtain its bulk form.
The thermal, acoustic, and hygroscopic properties of cellulose insulation recognized for over 100 years in countries accustomed to extreme temperature variations (Finland, Canada). It is also one of the oldest bio-based insulation materials.

Savings achieved with cellulose insulation
Several studies have demonstrated the savings achieved through insulation with cellulose insulation. For example, ADEME has shown that exterior insulation with cellulose insulation reduce energy consumption by 30%.
Return on investment for cellulose insulation
Accuracy of long-term savings
While the initial investment for installing cellulose insulation seem high, today the cost is similar to that of blown mineral wool. In addition, the long-term savings are significant. Thanks to reduced energy consumption, the investment can be recouped in just a few years.
Various factors influencing return on investment
Several factors can influence the return on investment of cellulose insulation. These include energy prices, the climate of the region, the quality of the installation, and the use of the building.
Comparison with other insulation materials
Compared to other insulation materials, cellulose insulation excellent value for money. It is the least expensive bio-based insulation for attic spaces. Furthermore, its cost is similar to that of glass wool or rock wool, while offering better thermal comfort.
